Journal ArticleDOI
Refractive index engineering with subwavelength gratings for efficient microphotonic couplers and planar waveguide multiplexers
Pavel Cheben,Przemek J. Bock,Jens H. Schmid,Jean Lapointe,Siegfried Janz,Dan-Xia Xu,Adam Densmore,André Delâge,Boris Lamontagne,Trevor J. Hall +9 more
TL;DR: Two experimental examples of refractive index engineering are demonstrated, namely, a microphotonic fiber-chip coupler with a coupling loss as small as -0.9dB and minimal wavelength dependence and a planar waveguide multiplexer with SWG nanostructure, which acts as a slab waveguide for light diffracted by the grating, while at the same time acting as a lateral cladding for the strip waveguide.
Journal ArticleDOI
A Silicon-on-Insulator Photonic Wire Based Evanescent Field Sensor
Adam Densmore,Dan-Xia Xu,Philip Waldron,Siegfried Janz,Pavel Cheben,Jean Lapointe,Andre Delage,Boris Lamontagne,Jens H. Schmid,E. Post +9 more
TL;DR: In this paper, a Si photonic wire waveguide was incorporated into a Mach-Zehnder interferometer based sensor, configured to monitor the index change of a homogeneous solution.
Journal ArticleDOI
A high-resolution silicon-on-insulator arrayed waveguide grating microspectrometer with sub-micrometer aperture waveguides.
Pavel Cheben,Jens H. Schmid,André Delâge,Adam Densmore,Siegfried Janz,Boris Lamontagne,Jean Lapointe,E. Post,Philip Waldron,Dan-Xia Xu +9 more
TL;DR: A 50-channel high-resolution arrayed waveguide grating microspectrometer with a 0.2 nm channel spacing on a silicon-on-insulator (SOI) platform with high channel density and spectral resolution is demonstrated.
Journal ArticleDOI
Spiral-path high-sensitivity silicon photonic wire molecular sensor with temperature-independent response
Adam Densmore,Dan-Xia Xu,Siegfried Janz,Philip Waldron,T. Mischki,Gregory P. Lopinski,André Delâge,Jean Lapointe,Pavel Cheben,Boris Lamontagne,Jens H. Schmid +10 more
TL;DR: A new silicon photonic wire waveguide evanescent field (PWEF) sensor that exploits the strong evanescence field of the transverse magnetic mode of this high-index-contrast, submicrometer-dimension waveguide is demonstrated with near temperature-independent response.
Journal ArticleDOI
Monolithic integrated wavelength demultiplexer based on a waveguide Rowland circle grating in InGaAsP/lnP
TL;DR: In this paper, the authors presented detailed modeling and experimental results for an improved design of an InGaAsP-InP wavelength demultiplexer based on a monolithically integrated Rowland circle grating.
